The Pimoroni Unicorn HAT Mini is a compact 17 × 7 RGB LED matrix (119 LEDs) with four tactile buttons for the Raspberry Pi. Each LED is individually controllable in colour and brightness, making it ideal for displaying animations, scrolling text, simple images, and interactive visualisations.

The header comes pre-attached — no soldering required. Simply plug it onto any Raspberry Pi with a 40-pin GPIO header and install the Python library to get started.
